To @ZZ 'whom it may concern: y

Be it known that I, FRANKLIN W. OEHRLE, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented an Improvement in Machines for Making Ornamental Rope or Cord, of which the following is a specication.

My invention relates to machines employed in the manufacture of ornamental ropes or cords, and it has for one purpose and object the simplication of the construction of such machines.

Although relating enerally to machines of the character speci ed, the specific object of the construction illustrated herein is to provide a convenient and effective form of means for holding the former in stationary position, around which former the ornamental loop threads are coiled, and also for assisting in the removal of the said coiled ornamental threads from said former.

One form of `a convenient embodiment of a construction adapted for these purposes is illustrated in the accompanying drawings, but it will be understood that changes in the details of construction may be `made within the scope of the claims without departing from my invention.

In the drawings gy Figure 1 is a view partly in side elevation and partly in vertical longitudinal section;

Fig. 2 is an end elevation looking toward the left in Fig. 1;

Fig. 3 is a perspective View of the former separated from the rest of the mechanism;

Fig. 4 is a longitudinal sectional View of the inner thread guide and the former secured thereto; and

Fig. 5 is a view showing a modication of means for securing the former in position.

In order that the drawings may be as simple as possible, consistent with a clear showing of my invention, I have omitted therefrom the parts of the machine which are not essential to the illustration and proper understanding of my invention For instance, I have omitted the rack upon which the spools are supported from which the ornamental strands or threads which enter into the construction of the rope are supplied, and I have also omitted the twister dev ice which. is of known construction and which operates in a known manner:

In the drawings, 1 designates the frame of the machine, and 2, 3 and 4 designate uprights or standards thereon.

The standards 3 are provided with bearings 5 in which the revoluble member 6 is mounted. The member 6 is provided with iying arms 7 and 8, two of such arms being provided for the purpose of maintainng the balance of the said revoluble mem# 10 designates the spool from which the inner binding thread 11 is supplied. The said spool preferably is secured upon a sleeve 12 which is loosely and revolubly mounted upon the cylindrical hollow bearing 13 which is firmly secured in an opening 14 in the upright 2 by means of a bind ing screw 15.

The binding thread 11 passes from the spool 10 through loop guides 16 upon the arm 7 and thence through an opening 20 in the guide member 21, which opening alines with the. openinV 22 in the former 23 secured to the mem er 21. The member 21 is loosely held in an opening 24 in the plugs or blocks 25 and 26 secured by means of screws 27 (only two of which are shown) in the revoluble member 6. y

The guide member 21 is held in the said plug or blocks 25 and 26 by means of ball earings 28 which fit partly in a semi-oircular groove 29 around the said guide member and in a semi-circular groove 30 in the opening or hole 24 through the said plugs or blocks 25 and 26 at the line of contact between the said blocks. The said blocks ma y be secured together by screws (not shown) if desired.

23 designates a former which is of Hat tongue like shape which is detachably se'-J cured by means of a binding screw to the projecting end of the guide member 21. For the purpose of holding the said former against rotation (and in the construction illustrated the guide member 21 also being held against rotation by the same means,) I have provided holding rollers 35 and 36 between which the tongue-like former projects. The said rollers are journaled in bearings 37 and 38 mounted in slots 39 upon the upright members 4.

The bearings 3S are connected to the lower ends of rods l0 which are guided in holes or openingsl throughthe plates 41. Springs 4-2 are located between the said plates 41 and the said bearings 38 whereby the roller 36 is held downwardly by a spring action.

A. driving gear 4,5 ie provided. nnen the Shaft of one'of the said rollers which gear ie itself driven from any source of power not eliown- Been of the Shafts' of the Said. rollers 35 and 36` is provided with gear wheels 4,6 and 477 which intermesh whereby the driving of one of said shafts causes revolution of both of the Said rollers 3,5, and 36. Such revolution is for` a purpose to be hereinafter referred to.

By reason of, the. feet that the. tongue-like former 23 is flattened, as indicatechit is obvious` that by locating they end thereof between the Said rollers, the latter hold the same against revolutioninotwithstanding the levolnti'onof, the member G.

The. strands or threads from which the ornamental loops are formed are taken from spools supported upon racks 0r in any other suitable manner (not shown) and extend through the guide members 5,0.v rear end o'l' the said guide member 50 is connected to a hOliZontalpivot 51 which is in turn supported upon the upper end of the vertical, pivoted member 52 which is supported in the tubular bearing 53 which bearing is secured` as indicated at 54ste a flange upon the lower end olf the upright 2. The vertical pivoted member.` 52 is held in the said bearing by means of a pin 5,5.

rIhe intersection of. the axes of the pivots 51 and 52 is at a point o o-axial with the axis of the revoluble member 6, and from the said point the member 50V extends at an angle to the axis of the saidfrevoluble member to a point beyond theiorward end of the latter. The length of the projection of the guide tube 50 beyond the revoluble member 6 is such that its revolution with the revoluble member 6 causes the winding or coiling of the loop strands or threads around the tongue-.like `former 23 as is clearly indicated in Fig. l of the drawings.

The outside binding1 thread 60 which coacts with the inner binding thread 11 may be of any suitable material and is supplied from, a spooll not Shown and extends around the roller 35 being positioned in a groove 61 therein.

The forward ends of the binding threads 11 and 60 are connected to a twister (not shown) which is caused to travel away from the said former and at the same time twist the said binding threads together in a known manner and thereby bind one side of the walls of the coiled ornamental threads or strands between the said binding threads, the said coils extending laterally from the said threads and therearound in the form of a continuous spiral.

The opposite edges of the flattened former arel inclined so that the tendency is for the threads coiled upon said former to slip therefrom, and the rotation of the roll ers 35 and 36 assists in causing the coiled threads to be fed for-ward and 0E ot the said tonguelike former 2,3` and by reason of the fact, that the upper one of the rolle ie Spring- PITeSSled but iS Velteelly movable. the Seid rollers may be separated so as to accommodate and coperate with foriners of different thicknesses and also to permit the use of thicker threads or Strands to forni the orneA mental loops oi' a greater number of strands in which case the Jthickness of the loop strands wound around the former would be greater.

Fig. 5 I have shown a modification of the means for securing the inner thread guide and former to the revoluhle member 6. A In said Fig. 5, designates a plug having a central opening 66 therein through which the guide member 67 isl inserted. The former 23 is of the saine construction and is supported upon the member 67 in the same manner as illustrated in previous figures.

`The member 67 is loose in the opening 66 andis heldtherein by means of a shoulder 6,3 formed thereon. To the inner end of the member 67 I have secured a sleeye 70 which prevents the removal of the member 67 from the opening 66 without first 4removing the said sleeve.

The arrangement illustrated in Fig. 5 is economical and isat the same time eilicient.

Having thus explained the nature of my said invention and described some of the ways of making and using the same although without attempting to set forth all of the forms in which it may be made or all the modes oi its use, what I claim is 1. In a machine for making ornamental rope or cord, the combination of a revoluble member, a former supported upon the said revoluble member, and means separate from and independent of said revoluble member for holding the said former in stationary position, means ior` supporting an outer binding thread in operative relation to said :Eormeigan inner binding thread extending through said, formerv and being supported winding the loop threads or strands around the said former and around a portion of the said inner binding thread, a revoluble means for supporting a supply of the inner binding thread, and means for drawing oil' the said inner binding thread and thereby causing the said revoluble inner binding thread supporting means to revolve in the same direction as the supporting and guiding device for the loop threads or strands.
